DAVID P. SIMS, OF LINCOLN, NEBRASKA, ASSIGNOR TO THE SIMS HYDRAULIC ENGINE COMPANY, OF SAME PLACE.

IM PACT WATER-MOTOR.

SPECIFICATION forming part of Letters Patent N 0. 644,833, dated March 6, 1900.

Application filed November 18, 1898- Serial No. 696,830. (No model.)

To all whom, it may concern.-

Beit known that I, DAVID P. SIMS, a citizen of the United States of America, residing at Lincoln, in the county of Lancaster and State of Nebraska, have invented certain new and useful Improvements in ImpactW'ater-lvlotors; and I do hereby declare the following to be a full, clear, and exact description of my invention, such as will enable skilful mechanics to construct the same, by reference to the accompanying drawings, and to letters of reference marked thereon, which form part of this specification.

Theobject of this invention is to provide a motor of which the power to operate shall be water under pressure, the power of which may be transmitted to a water-wheel, which it causes to revolve either to the right or left, as the operator may wish.

These motors will be of special value to dentists to drive their dental engines and lathes, being entirely under their control by means of a foot-switch, by which the motor is started, stopped, reversed, and the rate of speed controlled.

In the accompanying drawings, forming part of this specification, Figure 1 is a verti cal section through the valve-chamber. Fig. 2 is a sectional view through one of the buckets on the rotary water-wheel. Fig. 3 is a top plan view of a bucket. Fig. 4 is a sectional view through a portion of a bucket. Fig. 5 is a detail View of a clamping member. Fig. 6 is a vertical section through the valve-chamber and water-wheel. Fig. 7 is a sectional view through the water-wheel chamber and nozzles leading thereto, the waterwheel being shown in elevation. Fig. Sis a detail view of an apertured disk. Fig. 9 is a detail view of a treadle mechanism. Fig. 10 is a cross-sectional view through the treadle. Fig. 11 is a sectional viewthrough the treadle and pulley, and Fig. 12 is a top plan view of the treadle.

Reference now being had to the details of the drawings by letter, i) designates the base of the water-chamber, having a water-inlet d and outlets 0 and g. Over the outlet passageways are the valves 0, made of leather or other suitable material and having corresponding ends fixed to the inner circumference of the water-chamber by means of the clamp-brackets (1, held to the chamber by screws m. Mounted in the side walls of the water-chamber is the shaft 11, on which are lateral arms T, and connecting each end of an arm to a free end of a valve 0 is a chain 0". Over the outlet passage-ways g and 0 are the disks 2", having series of different-sized apertures vi therein, so as to allow the supply of water to gradually enter the passage-Ways leading to the water-wheel. Connecting the passage Ways with the pipes Z are unions 70, said pipes having nozzles to, as shown, which enter aper tures on opposite sides of the casing y, which contains the water-Wheel. Upwardly and outwardly inclined ears a on the casing adjacent to said apertures are provided, the upper surfaces of which ears are continuous with the lower margins of the inclined apertures in which the nozzles engage and serve to retain the latter in the positions shown in Fig. 7 of the drawings. I Mounted in the side walls of said chamber is a shaft p, on which is keyed a water-wheel h, having a series of buckets or pockets 6 about its circumference, which buckets are S-shaped in end or top elevation, as shown in Fig. 3. These 8* shaped or double buckets have their upper free edges slightly curved, as shown in Figs. 7 and 4, to receive the full force of the water when turned'on from either nozzle.

Mounted on the shaft 92 is a pulleyj, grooved and held to said shaft by means of a key R. Access is had to the interior of the waterchamber by means of removing the threaded disk or plate N. The shaft or may be oiled through duct M.

For operating the pulley which actuates the valves in the water-chamber I provide a 0 treadle '10, having ears w, pivoted to the up rights 0 on the plate 12. At one end of said treadle is a lug 10 having an elongated slot 10 in which slot a-lug X, carried by the pulley X, engages. This pulley X, which 95 has a grooved circumference, is mounted on a stub-shaft X mounted in the upright portion of the plate '0. An endless cable Y passes about the pulleys X and j, and by tilting said treadle the pulley j will be rocked 10o backward and forward and the valves 0 alternately opened and closed when it is demounted thereon, the treadle having a lug @0 with elongated slot to therein, the pulley X and plate supporting same, the lug X carried by the pulley X and engaging in said slot, and the cable passing about said pulleys, as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
